WS6 isa fat boy. I vote no on that Chad.
I'd like to see you do the C5. That's the only Vette that made me want a Vette. Viper guys are largely dorks -- (even though you're already a dork). LOL
Go for the C5. Or save your money and race people w/ your ATM receipt. That's always smart.
The s2k will likely not sell w/out being parted out (just being honest) unless you take a BEATING and lose over 50% of your investment. Stick a 9 inch under it and then keep that as your "race" car. S/C the current Vette just for giggles and call it a day.
